universal antenna

PRO: over the top packaging quite expensive
could have save a few bucks using PRIORITY TRIANGLE TUBE (FREE) arrived in a 18x 18x 40" heavy gauge box filled with peanuts almost could NOT find the slender whip antenna amongst this excessive packaging.
antenna arrived in perfect condition.
CON: the antenna does NOT stay screwed on and must be tightened daily as it does UNSCREW itself. I am contemplating lock-tite glue and hope that will work as a temporary fix
